555 Integrated Circuit Calculator.

Evaluate a number of common attributes related to the common 555 integrated circuit including time period, frequency, duty cycle, time spent low during each cycle, time spent high during each cycle.

TODO: This function should be broken into multiple smaller functions.

Parameters:

  • R (list[float, float] or tuple(float, float), optional) – List of 2 resistor which are need in configuring IC 555.

  • C (float, optional) – Capacitance between Threshold Pin and ground

  • f (float, optional) – Electrical system frequency in Hertz.

  • t_high (float, optional) – ON time of IC 555

  • t_low (float, optional) – OFF time of IC 555

Returns:

dict – “frequency”: frequency of oscilation of IC 555 “duty_cycle”: ration between ON time and total time “t_low”: ON time of IC 555 “t_high”: OFF time of IC 555

Return type:

“time_period”: Time period of oscillating IC 555
